tests/pxe-test: Add some extra tests
Previously virtio-net was only tested for ppc64 in "slow" mode. That
doesn't make much sense since virtio-net is used much more often in
practice than the spapr-vlan device which was tested always. So, move
virtio-net to always be tested on ppc64.
We had no tests at all for the q35 machine, which doesn't seem wise
given its increasing prominence. Add a couple of tests for it,
including testing the newer e1000e adapter.
